2. Claims. (01. 2409-110 The present invention relates to shades for lighting fixtures, and is more particularly directed toward glass shades suitable for use in wall pockets and the like.

The present invention contemplates a form of glass shade designed so as to be readily inserted into the metal or other parts of a lighting fixture wall bracket, and it is preferably provided with flanges extending laterally from the sides so as to engage in the pocket or recesses provided in the fixture.

A further object of the invention is to provide a translucent glass shade for wall brackets of generally semi-circular cross-section in horizontal planes tapering from the top to the bottom, and provided with side and end flanges adapted to be received in appropriately formed fixture parts.

The present application is a division of our nding application, Serial No. 136,001, filed April 23, 1927, for Lighting fixture wall brackets, on which Patent No. 1,818,119 was granted August 11, 1931.

The accompanying drawing shows, for the pur- 9253 pose of illustrating the invention, one of the many possible embodiments in which the invention may take form, it being understood that the drawing is illustrative of the invention rather than limiting to the same.

3: In the drawing:

Figure 1 is a perspective view of the glass shade;

Figure 2 is a front elevational view of a lighting fixture wall bracket, parts being broken away;-

Figure 3 is a vertical sectional view on the line 3-3 of Figure 2;

Figure 4 is a sectional view on the line 4-4 of Figure 3; and

Figure 5 is a sectional view taken on the line 549. 5-5 of Figure 2, to show tlfe method of inserting the glass pocket into the front plate, the back plate being omitted in this figure.

As shown in the drawing, a back plate of suitable outline and configuration is mounted on an outlet box or the like by suitable means such as a fixture stud indicated at 11. As shown more in detail in Figure 2, this back plate is comparatively wide at the top and narrows toward the bottom. To facilitate mounting it on the outlet box or other electrical fitting, the center of the back plate is raised as indicated at 12, and a hole 13 is provided for passing the fixture stud 11 through the back plate. As here shown, the upper edge 14 of the back plate is straight and arranged horizontal. Members 15 and 16 extend upwardly from the front face of the wall plate and are spaced a short distance in front of the rear surface of the wall plate.-

A forwardly extending lug 19 having a threaded aperture as indicated at 20 is carried adjacent the lower end of the back plate and a threaded hole 21 is placed as indicated in the lower end of the back plate.

The front plate 22, as here shown, has the same general shape as the back plate. It is provided with an upper cross bar 23 which is adapted to be placed behind the upwardly extending members 15 and 16 and to rest on the upper surface 14 of the back plate. It is also provided with downwardly converging side members 24 and 25 which are adapted to overlie the marginal portions of the back plate 10. As shown at 27, the upper outer portions of these side members are shaped so as to overlie the portion of, the back plate above the narrow shoulders 17 and 18 and to fit the back plate between these shoulders and the upper surface 14 so as to define the position of the front plate on the back plate and prevent its sliding about on the plate. The lower portions of the side members 24 and 25 have a rear face 29 adapted to rest on the front face of the back plate 10. The inner back face of these side members is spaced some distance in front of the surface 29, as indicated at 30 so as to provide space A for the flanges in the glass pocket to be described. Below the two side members 24 and 25, the plate is provided with a forwardly extending upwardly opening pocket 31 closed at the bottom as indicated in Figure 3. The lower end 32 of the front plate is provided with a screw hole-33.

The glass pocket or lamp cover 34 is shown more in detail in Figure 1. It is a general semicircular configuration as viewed from the top and is provided with side flanges 35 and 36, and a bottom flange 3'7. As here shown the upper ends 38 of the flanges 35 and 36 do not extend all the wayto the upper end 39 of the glass pocket.

It will be noted thatthe wall pocket above described is one wherein the glass shade intercepts all the light emitted in front of the wall except the upwardly directed light which passes out above the shade. No laterally directed light escapes behind the shade and hence no bright spots or sharp shadows are formed on the wall or adjacent objects. All the light which reaches the eye at ordinary angles of observation is softened and diffused by the glass.

In assembling thefixture, the socket maybe wired in and the back plate mounted on the outlet box in any convenient manner. The glass pocket may be inserted into the front plate aperture formed by the cross bar 23 and the side members 24 and 25in the following manner z The glass cover member is passed through the aperture in the front plate from the rear (as indicated in Figure 5) so as to bring the upper ends 38 of the'flanges 3 5 and 36 against the lower surfaces 23 in the upper rear corners of the front plate. The glass cover is then swung inwardly as indicated by the dotted circle to bring the' flanges and 36 against the-rear faces 30 on the side members 24 and 25 of'the front plate. In bringing the: glass pocket to this position, the lower flange 3'? is brought against the inner surface of the lamp socket pocket 31. After the glass member has been so inserted in the front plate, the cross bar 23 in the front plate is passec'tover behind the prongs 15 and 16 and the front plate allowed to hang in place. A screw 46 is passed through the hole; 33 and threaded into the hole 21 and secures the parts in place.

What is claimed is:

1. A translucent glass shade for wall pockets, said shade being of substantially semi-circular cross section in horizontal planes, tapering from the top toward the bottom and having laterally extending side flanges, the lower end of the shade having a semi-cylindrical flange.

2. A glass lamp shade of tapered shape and generally semi-circular cross section, the smaller end being slightly larger than a medium base lamp socket to accommodate such socket, the length and convexity being such as to accommodate and conceal a lamp bulb, the shade having at its opposite; edges laterally extending flanges in the axial, longitudinal plane of the shade.

3. A glass shade for lighting fixtures having a body portion of convex cross section and tapered shape, side flanges whose outer edges also taper relatively to the body of the shade, and an end flange extending from the smaller end.
